Cisco UCSC-GPU-A40 | A40 Graphics Card, 48GB GDDR6, 10752 CUDA Cores

Q: Which Cisco UCS servers support the UCSC-GPU-A40?
A: The UCSC-GPU-A40 is compatible with Cisco UCS C240 M6 and M7 rack servers, as well as UCS X-Series modular systems. It requires x16 PCIe slots and can be installed in Riser 1A slot 2, Riser 2A slot 5, or Riser 3C slot 7. Each server can support up to three of these double-wide GPUs, and minimum CIMC/BIOS version 4.2(2f) is required.

Q: What workloads is the A40 optimized for?
A: The A40 is designed for demanding visual computing, AI inference and training, data science, virtual workstations, real-time ray tracing, 3D rendering, CAD/CAE simulations, and high-performance computing. It combines professional graphics capabilities with powerful compute and AI acceleration, making it suitable for mixed workload environments.

Q: Does the UCSC-GPU-A40 support NVLink?
A: Yes, the A40 supports NVLink technology. Two A40 GPUs can be connected via NVLink to scale performance and memory capacity from 48GB to 96GB, providing increased GPU-to-GPU interconnect bandwidth for larger datasets and accelerated graphics and compute workloads. Application support for NVLink must be verified.

Q: What are the power and cooling requirements?
A: The UCSC-GPU-A40 has a thermal design power (TDP) of 300W and features passive cooling. It requires adequate server airflow and power supply capacity. The dual-slot, full-height full-length form factor means it occupies two adjacent PCIe slots. Specific power cables may be required depending on the server model.

Q: Can the DisplayPort outputs be used for direct display connection?
A: The A40 includes three DisplayPort outputs, but by default display port functionality is disabled on Cisco servers. System output is sent to the server KVM. If you need to use the GPU DisplayPort outputs, they can be enabled using the Cisco displaymodeselector tool available through Cisco support channels.
